Обсуждение: How do I return more than one value in a postgresql pl/pgsql procedure?

Hello!

I am have been trying to figure out how I can get a pl/pgsql procedure 
to return more than one variable or perhaps a row. A procedure you 
create can accept more than one variable, I don't see why it shoudn't be 
able to return more than one variable in some fashion.I read rumors that  pl/pgsql can return rows (which would contain
oneor more variables 
 
per row), but I didn't find hard examples of how to do it.

What table lists the stored procedures you created with pl/pgsql or 
pl/perl? I was trying to find it with /dS in psql, but I didn't see 
anything obvious.
Thanks!

See this:
http://developer.postgresql.org/docs/postgres/plpgsql-cursors.html

Especially the section "Using Cursors". This is the 7.3devel
documentation, but this section should work just as well for 7.2 (this
WON'T work for 7.1 and below).
